    • Overleving av makrell som er trengd i not 

      Huse, Irene; Saltskår, Jostein; Soldal, Aud Vold (Fisken og havet, Research report, 2008)
      Atlantic mackerel (Scomber scombrus L.) is extremely vulnerable towards handling and stress, which makes it difficult to investigate its survival after contact with fishing gear. By using a new method, where mackerel were ...

    • Overleving av makrell som er trengd i not 

      Huse, Irene; Saltskår, Jostein; Soldal, Aud Vold (Rapport fra havforskningen, Working paper, 2007-10)
      Atlantisk makrell (Scomber scombrus L.) er ekstremt sårbar for handtering og stress, noko som gjer estimering av overleving etter reiskapskontakt vanskelig. Ein offshore metode der makrell har blitt overført frå not til ...

    • Overleving av torskefisk som unnslipper fra reketrål med Nordmørsrist 

      Soldal, Aud Vold (Fisken og havet, Research report, 1995)
      The survival of one year old cod (Gadus morhua), haddock (Melanogrammus aeglefrzus) and whiting (Merlangius merlangius) escaping from a shrimp trawl with a metal grid sorting device (the Nordmøre grid) was studied during ...
